Julian Wells was a writer of dark non-fiction works that detailed some of the worst crimes of the 20th Century. Was it this exploration of man's inhumanity to man that caused him to take his own life?

When his body is found in a boat drifting in a pond in Montauk, New York, his best friend, the literary critic Philip Anders, begins to reread his work in order to prepare a eulogy.
